The National September 11 Memorial & Museum holds its dedication today, deep beneath Ground Zero, 12½ years after the terrorist attacks. The museum spans seven stories, from its surface entrance pavilion down to bedrock. Its subterranean galleries include a 17-foot-high cross-section of steel I-beams that stood after the attack and several other monumental artifacts. Attending are President Obama, first lady Michelle Obama, former New York City mayor Rudy Giuliani, 9/11 families, rescuers and survivors.

2. Fast food workers' strike goes global

Fast Food Forward, which represents U.S. fast-food workers, plans a nationwide strike Thursday. In addition, workers from dozens of countries on six continents will hold protests at McDonald's, Burger King and KFC outlets. It is not known how many workers will strike, but thousands of the nation's estimated 4 million fast-food workers are expected to take part. The strikers are demanding a wage of $15 per hour. "We've gone global," said Ashley Cathey, a McDonald's employee from Memphis. "Our fight has inspired workers around the world to come together."

3. FCC looks at airwave spectrum auction

The Federal Communications Commission will consider proposals for rules governing an "incentive auction" of airwave spectrum set to take place next year. The basic idea is simple. The FCC wants TV stations to sell it back licenses to low band spectrum they don't use. Those low bandwidths are the most valuable to wireless carriers, because those wavelengths can go long distances and reach deep into buildings, meaning fewer dead spots for cellphones. Those bits of spectrum will then be auctioned off so carriers in the booming wireless market can expand their service.

4. VA Secretary Eric Shinseki in Senate hot seat

Veteran Affairs Secretary Eric Shinseki will appear before a Senate committee that is looking into charges that veterans have waited months to be seen by a doctor. In dozens of cases in recent years, some died before treatment was provided. Earlier this year, the VA said its own internal review found 23 veterans deaths in the past three to four years that were linked to delays in cancer screenings. There have been calls recently from some sectors, including the American Legion, for Shinseki to step down.
